Helping more people around the world to have access to safe drinking water is one of the greatest challenges of the 21st century.
But a company from Carmarthenshire are aiming to improve the situation, with their pioneering technology for purifying water.
The technology takes three minutes to clean the water. We've sped up that process for you in the video below, so you can see how it works.

A north Wales airfield has been highlighted as a possible location for a UK 'spaceport'.
Llanbedr airfield, in Gwynedd, is being considered along with 7 other sites by the UK Government. If chosen, it would become Britain's first spaceport and could become a base for commercial flights from 2018.
UK Business Secretary, Vince Cable, said: "Space is big business for the UK. It already contributes £11.3 billion to the economy each year, supporting nearly 35,000 jobs.
"That’s why it’s important for us to prepare the UK for new launcher technology and take steps towards meeting our ambition of establishing the first British spaceport by 2018."
Other sites that are under consideration include Glasgow and Newquay.

A car aiming to travel at 1000mph is nearing completion helped by the expertise of engineers at Swansea University.
They blended Formula 1, aerospace and rocket technology to model Bloodhound SSC's design.
The Swansea University team also designed the Thrust supersonic car which hit 763mph in 1997. The record hasn't been beaten.
Bloodhound SSC has a Rolls Royce Typhoon fighter jet engine and a rocket below. A Formula 1 car engine pumps the fuel.
First Minister Carwyn Jones says the Welsh Government will start using the .wales and .cymru domain names from next year.
Businesses in Wales will be able to apply for the addresses from the autumn, with a wider roll out beginning in 2015.
Ann Beynon, BT's Director for Wales, is calling for more women to take up engineering. It comes as the firm announced it was creating up to 190 new engineering jobs.
They say they particularly want women to apply, but when asked how many they expected to take on, they admitted it would probably be less than 20:
I'd love it to be much more than that - but we need women to apply - and what happens is women don't even apply, they don't actually understand that these jobs are jobs they could be doing. When we get women they are brilliant, so it's obvious they are able to do the work but maybe that perception isn't there as it should be."
BT is creating up to 190 new engineering jobs in Wales as part of a major UK-wide recruitment drive.
The company says the engineers will help improve customer service and continue the high-speed fibre broadband roll-out.
It is particularly keen to recruit in communities including Wrexham, Bangor, Cardigan, Abergavenny, Carmarthen, Machynlleth, Llandrindod Wells, Presteigne, Newtown, Usk, Caernarfon, Llanberis, Llanwnda, Pwllheli, Rhyl, Bethesda, Fishguard and Haverfordwest.
The .wales and .cymru addresses will boost Wales' visibility and help attract investment, says Ieuan Evans.
Over the past two years we have worked with Welsh businesses and organisations to create an opportunity to brand Wales online and to strengthen the visibility and use of the Welsh language on the internet.
The execution of the .cymru and .wales contracts has made this dream a reality. 2014 is the year that we take Wales into the digital future.
